Letter of Volatility for ASUS NUC Mini PCs
Technical guide detailing memory volatility and data retention for various ASUS NUC Mini PCs, Kits, and Boards. Learn how to clear volatile and non-volatile memory components for data security.
Table of contents
Important Information
This document provides technical specifications regarding memory volatility for various ASUS NUC products. It is intended for users who need to understand data retention and security procedures for these devices. It covers multiple generations of NUC Mini PCs, Kits, and Boards, including the NUC 12, 13, 14, and 15 series.
Understanding Memory Volatility
ASUS NUC products utilize both volatile and non-volatile components. It is critical to understand the difference for data security purposes:
- Volatile components: These components lose their data immediately after power is removed from the system.
- Non-volatile (NV) components: These components continue to retain their data even after power is removed from the component.
Power States
The system operates in different ACPI power states, which affect data retention:
- S0 (Working state): The system is active, and dynamic RAM is maintained.
- S0iX (Modern Standby): Enables instant on/off experience while maintaining low power and network connectivity.
- S4 (Hibernate): Suspend to disk. Minimal power is used, and dynamic RAM is not maintained.
- S5 (Soft off): The system is shut off. No data remains in cache or memory.
Data Clearing Procedures
To clear data from specific components, follow these general guidelines based on the component type:
- CMOS: Remove power and the onboard Coin Cell battery.
- SSD: Physically remove the module or delete data via software.
- TPM: Use the BIOS option and motherboard jumpers to clear.
- Cache/RAM: Remove power to the board.
Always consult the specific table for your NUC model in the document to confirm the exact remedial action required for each component.

Practical help
Common problems
How to clear CMOS data
Remove power from the system and remove the onboard Coin Cell battery.
How to clear SSD data
Physically remove the M.2 module or delete the data using software tools.
How to clear TPM data
Use the BIOS option and the designated jumper on the motherboard to clear.
How to clear RAM/Cache data
Remove power to the board.
Before use
- Identify your specific NUC model from the contents list.
- Verify if the component you are concerned about is volatile or non-volatile.
- Check the 'Remedial Action' column for your specific model to ensure proper data clearing.
Specs in practice
- Volatile Memory
- Memory that loses data immediately when power is removed (e.g., RAM, Cache).
- Non-Volatile Memory
- Memory that retains data after power is removed (e.g., BIOS, SSD).
Model compatibility
- This document applies to a wide range of ASUS NUC 12, 13, 14, and 15 series Mini PCs, Kits, and Boards.
